Mercury 15HP 15EXLHPT ProKicker EFI Outboard

With a 25-inch extra-long shaft, the Mercury 15HP 15EXLHPT ProKicker EFI Outboard reaches deeper than Mercury's shorter kicker shafts, carrying over the same four-blade high-thrust wheel this ProKicker line uses for trolling, along with console-style steering and a key-turn start. It weighs 114 pounds.

Picking the right shaft length

Extra-long shafts like this 25-inch one are meant for kicker brackets mounted well above the waterline, such as those on larger offshore or bay boats; too short a shaft on that kind of bracket leaves the prop skimming near the surface instead of biting into clean water. Mercury builds this same ProKicker block with other shaft lengths for lower-mounted brackets, so match the shaft to your own bracket height rather than your main engine's shaft.

Built to push, not race

The four-blade high-thrust prop trades top speed for steady low-RPM thrust, which suits trolling and holding position far better than a standard three-blade wheel would. Remote throttle control pairs this motor with a console-mounted lever rather than a tiller arm, so confirm your boat's rigging matches before ordering.

Running two engines together

A kicker like this one is typically wired on its own separate fuel and electrical circuits from the main outboard, which keeps troubleshooting simpler if either engine develops a problem; keep the two systems independent rather than sharing a single battery or fuel line if you can.

Is the warranty the same as other 15 HP Mercury models? Yes, this new engine carries Mercury's standard three-year factory warranty.
